In this video I explain some advantages and disadvantages of brand microscopes (Olympus, Leica, Nikon, Zeiss) compared to no-name microscopes. Overall, brand microscopes have a high mechanical and opical quality and long-life. But this comes at a price. Branded microscopes are significantly more expensive. Not every amateur microscopist might need the mechanical or optical quality (or have the money!). I generally recommend, that beginners start with lower-cost microscopes and then move on to better microscopes later on, when they have gained more experience, should they even desire a brand microscope at all. Often a low-cost microscope will be fine for them.
